前 言钢材具有高抗拉性和优良的延展性 ,混凝土材料具有很强的抗压能力和抗腐蚀能力 ,这两种材料的合理结合所产生的新性能在钢筋混凝土结构中早已为人们所知。钢 -混凝土组合结构具有以下优点 :(1)截面尺寸小 ,承载力高 ;(2 )延展性好 ,抗震能力强 ;(3)外包混凝土和内填混凝?
Foreword Steel has high tensile strength and excellent ductility, concrete materials have strong compressive strength and corrosion resistance, the combination of these two materials resulting from the new properties in the reinforced concrete structure has long been known. Steel-concrete composite structure has the following advantages: (1) small cross-section size and high bearing capacity; (2) good ductility and strong earthquake resistance; (3)
